[QUOTE="PV Audio, post: 2678811, member: 554493"] Hey all. I just "installed" a kid's new sub and amp into his truck, and while the sub is moving well, there is nearly no output at all. It sounds as though it's out of phase, but it isn't because I checked. The only thing I noticed was that we were getting TREMENDOUS impedance rise when we fired it up. At baseline, it was seeing 1.1 ohms (which is correct), but when we turned on the car, it immediately jumped to 15-20 ohms. When playing music, it would peak up into the 50s and 60s, while staying around 20 for much of the time. What could be the problem? It's getting 13v baseline, and 14.1 when the car's on and playing. The sub is a dual 2 ohm Brahma MK2, and the amp is a refurb Orion 1200d. The amp isn't a factory refurb, which I think may be part of the problem (the amp I mean), but I don't do much electrical or install work, just designs and building. And help would be appreciated.
